5 Common Signs You Must Get Your Water Heater Replaced

Water is an indispensable resource for any household because it is used in various applications, such as bathing, washing dishes, and watering plants. However, not everyone can tolerate cold water, so many homeowners use a heater to warm it before using it. Water heaters come in different shapes and sizes and can be powered by electricity, gas, or solar energy.

A water heater is precisely what it sounds like: it provides a steady supply of hot water, which can be used for various purposes, typically in swimming pools, hot tubs, and other recreational areas. However, a heater can only work for so long until it needs replacement, which few homeowners only know of because they do not know the signs to look for.

With this in mind, here are some telltale signs your water heater must be replaced:

#1 – Your Heater Is Old

One of the most obvious signs that your water heater needs replacement is its age. Most water heaters are designed to last about 10 years, with some lasting up to 15 years. If your water heater is older than that, it’s probably time to replace it. If your heater is over 15 years old, it is time to replace it.

In addition to its age, you should also consider how much use the heater has seen over the years. If your heater has been used frequently, it may need to be replaced sooner than those with less use.

#2 – Frequent Leaks

Heater leaks are bound to happen and can be fixed most of the time. However, frequent leaks are problematic because they can damage your home extensively through water damage and mold growth. If your water heater leaks frequently, it’s a good indication that it needs to be replaced.

You must inspect the area around the water heater for any signs of corrosion. Corrosion can cause the tank to leak and should be addressed immediately. If the corrosion is extensive, it’s a good indication that the water heater needs to be replaced.

#3 – Rusty or Dirty Water Comes Out

If you notice that the water coming out of your water heater is rusty or dirty, it is a sign that it needs to be replaced. Rust and dirt in your water can be caused by a few different things, which can damage your water heater, including corrosion, scale buildup, and sediment buildup.

Scale buildup occurs when minerals like calcium, magnesium, and iron build up inside your water heater tank and pipes. Over time, this scale can corrode the metal and cause it to rust, which can enter the water. Conversely, sediments can build up in your water heater tank and pipes over time and can cause your water to become discolored.

#4 – You Hear Loud Noises

When you hear loud noises from your water heater, you must get it checked because it could signal a severe problem. Loud noises coming from your water heater are usually due to sediment buildup in the tank, which can cause the water heater to overheat and the tank to crack. It can also be caused by a broken heating element or a malfunctioning pressure relief valve.

#5 – It Is No Longer Energy Efficient

Energy efficiency is crucial when using a water heater because it can save you money and reduce your carbon footprint. If your water heater is no longer energy efficient, it could be a sign that something is wrong.

As mentioned, age plays a factor because older water heaters are less efficient than newer ones. However, another sign that your water heater is no longer energy efficient is if you notice an increase in your energy bills. If you have recently seen a sudden spike in your energy bills, it could be because your water heater is no longer running as efficiently as it should.


If you notice any of these signs, it is best to call a qualified technician to inspect your water heater and determine if it needs to be replaced. Finding the best replacement for your heater will be tricky, so professional input will be highly beneficial. This way, you can get the most energy-efficient water heater available and save money in the long run.
